T wmzp STATES FRIEDRICH STENDEBACH, or LEIPZIG-GOHLIS, Gam ian j FIREARM WITH DROP-DOWN.BARREL.
Application filed May 20,
T all whom it may concern:
Be it known-that I, FRIEDRICH STEXDE- BACH, a subject of the Emperor of Germany, residing at \Yeinligstrasse, Leipzig-Golrlis, Germany, have invented certain new and useful Improvements in Firearms with Drop- Down Barrels; and I do hereby declare the following to be a full. clear, and exact descript-hon of the invention, such as will enable others skilled in the art to which it apper-- tains to make and use the same.
This invention relates toan arrangement of the breech in fire-arms with drop-down ,,barrels, the advantage of which is that when the barrel is tilted the movable breech-piece does not come out of the breech box and insures the barrel being firmly held. In the case of fire arms with pivots seated in or below the axis of the bore it also insures an easy opening of the breech when the maximum charges are used, as the jamming observable in such weapons has hitherto made the opening of the breech after the firing more difficult.
Figure 1 of the drawings is a longitudinal section through the breech box, the barrel being in the position for firing, Fig. 2 a similar section, the barrel being tilted down.
The barrel 1) is arranged so that it can be tilted around a pin a, which is situated for example a-bove the axis of the bore of the barre b. On the back part of the barrel ribs (1 are arranged which move in suitable grooves in the breech box.
The breech piece 71 is pivotally seated on a pin i which is below the axis of the bore of the barrel b and as near as possible to the bottom end thereof as well as to the bottom of the cartridge. The position of the pin 1'. is important as regards the easv opening of the breech after the firing, for only if the pin i as nearly as possible in the )lane of the breech piece and as far as pos ible below the axis of the bore of the barrel will the breech piece swing at once from the bottom of the cartridge when the breech is opened. The back surface of the breech piece It is of circular form, so that it can be turned in a lathe without trouble and with the greatest accuracy.
The inner surface of the fixed breech piece 71, which is towards the barrel is likewise hollowed out in circular form. Under the bottom m of the movable breech piece 71, which is slightly inclined forwards, is a sliding bolt n which is'suitably connected with the bolt f that engages in the lump g, in such almanner that when tl1e barrel b is locked the Specification of Letters Patent.
1901. seria1No.'3'i4,sds.
- locking of the movable breech piece it simultaneously effected. T he'part-p of t movable breech piece extended beyond t pin i projects under the barrel 1) (Fig. 1) b so that the projection orhook p is at a slig distance from the bottom of the barrel wh the barrel is locked, and that when the firi takes place the recoiling breech piece h ca not tilt the barrel from its-seating.
It is advisable to arrange the fixed brec piece 71, as a separate fitting in the bree box, so that it can be carefully turnedir lathe in the same manner as the back surf: oft-he movable breech piece h. In the c: of dr p down barrel fire arms with dou barr 1 it is further advisable to form 1 breech piece h in two'parts, so that evr barrel has, its own breech piece and so tl when the firing takes place the breech pi of the one barrel may not be forced by 1 other intbgan unfavorable position, wh may easily occur when a part is worn or wl the surfaces arerrot uniformly turned. If barrel is to be t-ilted, the bolts a are f pulled back and-thfebarrel can be ti ted wi out trouble. When the tilting takes place movable breech piece his forced back into breech box by the innerend of the barrel, 2 the hook p moved proportionally upwa-l \Vhen the breech is closed the lower enr the barrel rests on the hook and in this forces the breech piece h against the b end of the barrel. The final or comp: fixing of the breech new is only eff ec subse uently by its being locked thro' the bo t n.
What I claim and desire to secure .ters Patent is: a
1. In a drop-down barrel fire arm pivoted barrel, a breech piece pivot mounted below the axis of the bore of barrel, two locks, one for the barrel and for the breech iece, and means for actua the locks simu taneously.
2. In a drop-down barrel fire arlr pivoted barrel provided with a shoulde pivoted breech piece, two reciproca' locks for engaging with said shoulder the breech piece, respectively, and mean: reciprocating said locks simultaneously.
3. In a drop-down barrel fire arn pivoted barrel provided with a recessed jection, a )ivoted breech piece, a recipr tory lock for entering said recess, a pi1 the rear end of said lock, and a reciproca lock having its rear end mounted on sai( PATENT oFFioE.

and its forward end inclined for engagin with the breech piece, whereby the barre and the breech piece are simultaneously locked in their closed positions.
4. In a drop-down barrel firearm, a pivoted barrel, a stationary breech piece, a movable breech block pivoted thereto for closing the barrel, means for locking the barrel in firing position, independent means for locking the breech block in its closed position, and means for actuating both of said locking means.
5. In a firearm, a statlcnary breech P1606,
